ALVAH C. ROEBUCK, OF WOODSTOCK, ILLINOIS, ASSIGNOR TO WOODSTOCK TYPEWRITER V COMPANY, OF WOODSTOCK, ILLINOIS, A CORPORATION OF ILLINOIS.

TYPE-BAR SEGMENT.

To all whom it may concern:

Be it known that I, Anvan C. RoneUcK, a citizen of the 'lj nlted States, residing at Woodstock. in the county of McHenry and State of Illinois, have .invented certain new and the like from falling into the slots in T which the type bars are pivoted;

For the attainment of. this end and for the accomplishment of other new and useful'objects as will appear, the invention consists in the features of novelty in the con- ".struction, combination and arrangement of the several parts generally shown in the accompanying drawing and described in the specification, but more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a front elevation of a type bar segment constructed in accordance with the principles of my invention, towhiclr isconnected a type bar guide;

--Fig. 2 is a sectional view of the same taken .on the line 2-2 of Fig. 1.

Inmaki'ng erasures upon the platen of the ordinary visible typewriting machine,

the dust, dirt or grit from the erasure is i liable to'fall into the pivot slots of the type bars and to clog or interfere with the free .movem'entand action of the type bars. The

present invention comprises a structure in which a plurality of defiecting'surfaces are provided at the front of the type bar segment, so that any grit or dust falling from the erasure is most likely to strike one or vmore .of the deflecting surfaces and be thrown entirely clear of the slotted portion of the segment in which the type bars are pivoted.

type bar segment 4, preferably segmental in shape, is provided with a curved beveled surface 5 at about the center of its upper straight .edge. A type bar guide 6 is preferably secured to the upper side of the segment by means of fastening devices 7, and

comprises guides proper 8 at the other end,

and a peep sight 9. The'inclined or beveled deflecting surface 5 is preferably disposed Specificationof Letters Patent.

below the peep sight opening 9 and a deflecting surface 10 is disposed below the surface 5, .is curved outwardly and is rounded in the same direction as the outer edge of the segment. The segment is formed with an abutment 11 just below the deflecting surface 10, the type bars (shown in dotted outline)'being adapted to engage the abutment at the upper end of their stroke.

Below the abutment 11 is a reinforcement 12 of the segment 1, in which are a plurality of type bar slots '13 extending radially from the outer edge of the segment. The upper edge or surface of the slotted reinforcement is also rounded outwardly, forming a third deflecting surface 11 for throwing out any particles of dirt which may have passed the two other deflecting surfaces. T

The rearof the segment is formed with a groove 15, in. which the universal bar is adapted to engage, and with a groove 16 extending along adjacent the outer edge of the segment on the inside thereof, to seat a type bar pivot wire 17. The groove 16 is preferably formed with a slightly undercut portion 18 along the outer. side of the groove, and the pivot wire is maintained in position in the groove 16 by means of the adjusting screws 19, which abut the ends of the pivot wire from the opposite side of the segment 4, as shown in Fig. 1.

It will be seen that any grit or dirt falling from erasures is most likely to strike either the first deflecting surface 5, at the top of which might enter these slots is very small.

and is not enough to cause any serious detriment.

' What I claim 1s:

1. An upright type bar segment for only front strike typewriters having inclined de-' fleeting surfaces at the front of the se ment graduated in width and disposed one. elow I the otherr 2. An upright type bar segment for. a front strike typewriter'with three deflecting surfaces atsthe front of the segment arranged one in advance ofr-the other.

'3. An upright type bar segment withione Q beveledand two curved front deflecting surfaces at the front side of the segment.

i; In a type bar segmentfor front strike typewriters, an inclined deflecting surface ajacent'the top of the segment, a ty e bar abutment, and a curved deflecting snr ace at the upper edge of the abutment and below the inclined surface, all disposed on the front side of (the segment. a

5. An upright type ba'r segment for frontstrike typewriters, formed at the outer edge with a slotted reinforcement in which the type bars are pivoted, the slots being open at the top, the top reinforcement curving outwardly from the front .face of the seg-- ment to form a dirt deflecting surface, and

an abutment above the reinforcement against which thetype barsstrike, the abutment being formed integral with the segment and with a dirt-deflecting surface at the upper I side of the abutment.

6. Anupright type bar segment for front strike typewriters formed at the outer edge with a slotted reinforcement in which the type bars are pivoted, the slots being open at the top, the top of the-reinforcement curving outwardly from the front face of the segment to form a dirt deflecting surface an abutment above the reinforcement against which the type bars strike, the'abutment being formed integral withfthe segment and with a dirt deflectingsurface-at the :upper side of the abutment, -and another beveled deflecting surface above the abutment.

7 A type. bar 'segment'for' fronti strike typewriters having a slotted, reinforcement at the outer edge'ofthe segment," the reinthereto by a deflecting curve,"th e slots of the reinforcement extending through the extending portion. of the curveddeflecting surface,

and graduated 'defiectin'g'surfaces above the reinforcement.

In testimonywhereof I havesi-gned my name to this specification, in the presence of Y J. B. SwAH'rsTE T',
